10 Best Mini Split Ac Unit For Semi Truck 2026 in the United States

The Treeligo 12V Truck Air Conditioner is designed specifically for vehicles like semi-trucks, RVs, and construction equipment, offering a solid 12,000 BTU cooling capacity. This allows it to quickly lower the temperature inside your truck cab, which is especially beneficial for long hours on the road in hot weather. It uses inverter technology, enabling the compressor to adjust its speed based on cooling needs, which helps save battery power and ensures quiet operation at around 45 decibels—similar to a quiet conversation. The AC is powered by a 12-volt system compatible with your truck’s battery and can run with the engine off to reduce fuel consumption.

Installation is straightforward thanks to included accessories and instructions, and the durable ABS plastic housing resists corrosion and weather damage, making the unit suitable for harsh environments. While the energy efficiency is limited with a 1-star rating and a SEER of 1, indicating higher power consumption compared to other units, this may be a factor if you rely heavily on battery power without frequent engine running. The noise level, although relatively low, might still be noticeable in very quiet cabins.

The unit offers remote control and multiple operating modes (energy saving, sleep, powerful), adding convenience and flexibility. It also features a dehumidification function that can help reduce moisture inside the cabin. Backed by a 1-year warranty and positive customer feedback, it serves as a reliable cooling solution for truck drivers seeking easy installation and dependable performance, though it may not be the best option if minimizing battery drain over long periods is a priority.

This 12V DC mini-split air conditioner offers a solid 9000 BTU cooling capacity, which is a good fit for semi-trucks, RVs, and other heavy vehicles needing reliable cooling while parked or on the road. It runs directly off the vehicle’s 12V battery without requiring the engine to be on, helping reduce fuel use and pollution during breaks. The scroll compressor provides efficient and steady cooling performance. Noise is kept low at around 35 decibels, meaning it operates quietly enough not to disturb rest or communication inside the cab.

The unit supports split system installation, which typically means better airflow and easier maintenance compared to window units, but installation may require professional help. A remote control and panel buttons allow easy adjustment of temperature and fan speeds, adding convenience on the go. The unit also has rapid cooling and a 5-level airflow system with 360° rotating outlets for even temperature distribution. On the downside, its energy efficiency rating is modest at 2 stars and a SEER of 13, so it may draw relatively more power compared to higher-efficiency models. It demands a strong vehicle battery—over 200AH—to handle the 60-70 amps current draw, which is important for users to consider to avoid battery drain.

This air conditioner is practical and convenient for truck drivers or RV owners who want a quiet, effective cooling solution powered by their vehicle battery, but it requires attention to power supply and possibly professional installation.

The Aspligo 12V Truck Air Conditioner is a mini-split system designed for semi-trucks and similar vehicles like RVs, excavators, and buses. It offers a cooling capacity of 7200 BTU, which is effective for keeping the cabin comfortable in warm conditions. The unit runs on 12 volts, making it compatible with typical vehicle electrical systems. Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features. This unit is a practical choice for truck drivers or operators seeking reliable cooling with straightforward installation, provided refrigerant charging is appropriately managed.
